Answer:
C. Burning wood
Explanation:
BURNING. Burning is a non-reversible chemical change. When you burn wood, the carbon in the wood reacts with oxygen in the air to create ash and smoke, and energy in the form of light and heat. This is a permanent change that cannot be undone – you cannot turn ashes back into wood.
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere. Photosynthesis is part of the carbon cycle, and cellular respiration is not. (Only plants perform photosynthesis, and only animals perform cellular respiration )
Explanation:
Well it should be easy in my opinion ill just say its chemical energy because the chicken and the broth and noodles and vegies give you lots of energy exspecially if your gonna have seconds ;)
Answer:
compound 1 = 0.749gF / 1.0gl
compound 2 = 0.4489gF / 1.0gl
compound 3 = 1.047gF / 1.0gl
Explanation:
Given that;
compound mass of iodine in grams mass of fluorine in grams
1 4.75 3.56
2 7.64 3.43
3 9.41 9.86
a) Calculate the mass of fluorine per gram of iodine in each compound:
- compound 1
mass of Fluorine = (3.56gF / 4.75gF) * 1.0gl
= 0.749gF
Now RATIO = 0.749gF / 1.0gl
- compound 2
mass of Fluorine = (3.43gF / 7.64gF) * 1.0gl
= 0.4489gF
Now RATIO = 0.4489gF / 1.0gl
- compound 3
mass of Fluorine = (9.86gF / 9.41gF) * 1.0gl
= 1.047gF
Now RATIO = 1.047gF / 1.0gl
